Micro-extraction of urine and/or stomach contents and analysis by TLC Abstract Thin Layer Chromatography (TLC) is one of the oldest chromatographic techniques used for the identification of compounds and for determination of the presence of trace impurities. The aim of the experiment was to determine two unknown samples (X and Y) by comparing results to the known standard drugs‚ of which there was five‚ using a specific TLC method. The same technique was used for the determination of

Alkaline Phosphatase was isolated using various techniques. BCIP spot test was performed after the anion exchange chromatography was done and the fractions were collected. The picture of BCIP spot test of the 20 fractions can be seen in figure 1. The intensity of each spot was different from each other. The more intense color the spot was‚ the more concentrate the AP was. The fractions were chosen to combine together based on the intensity‚ which made the stage 4 enzyme. Different volumes in each

Can I print T Shirts using dye sublimation printing? Dye sublimation printed shirts have started to become rather popular‚ sublimation tends to makes the t shirts more wearable and comparably soft. Dye sublimation printer is basically a computerized printer that turns the printed image‚ mirror reverse‚ in the form of gas and with the use of heat transfers the gaseous dye on the cloth giving the print ‘a no hand feel’. This process makes the most vivid and real images to be printed on the t shirts

goal of this lab was to create and purify DHFR from BL21 ecoli using column chromatography. To know if we isolate DHFR their will be one band at 53 KD or above 50 KD and in our desalted eluate page should have the highestOD₂₈₀ which translates to the highest enzyme activity .Column chromatography is a method used to purify individual chemical compounds from mixtures of compounds. The main advantage of column chromatography is the relatively low-cost and disposability of the stationary phase used in

Abstract Pigments extracted from different greens have different polarities and may be different colors. Mixed pigments can be separated using chromatography paper. Chromatography paper is able to separate mixed pigments due to their polarity and solubility. Pigments of chlorophyll a‚ chlorophyll b and beta carotene will be separated on chromatography paper because each has its own polarity and solubility‚ which results in different distance traveled up the paper. Beta carotene is non-polar so it
